From the old town of Bilbao C 6313 runs north via Begoña to Munguía. From here it climbs, with many bends, to the ridge of Monte Acherre, from which there is a picturesque view of Bermeo; to the right is the hill of Sollube (684m/2244ft), with a television transmitter on the summit. The road then descends to Bermeo, beautifully situated on the slopes of the hill, its harbor crowded with colorful fishing boats.
Bermeo, originally a Roman foundation, is the most important fishing port on the Cantabrian coast. The Fisheries Museum has an interesting collection which includes models, fishing equipment and fittings from fishing boats. It is housed in the Torre Ercilla (now a protected monument), which was once occupied by the adventurer and poet Alonso de Ercilla (1533-94).
